Abstract (en)
[origin: US2002198350A1] Provided are a propylene homopolymer in which a melt tension (MT), a Z average molecular weight (Mz) and a melt index (MI) (g/10 minutes) are specifically related and in which a difference in eluting temperatures and a maximum eluting temperature in programmed temperature fractional chromatography and a propylene copolymer in which a comonomer is specific alpha-olefin and a content thereof falls in a specific range and in which a melt tension (MT), a Z average molecular weight (Mz) and a melt index (MI) (g/10 minutes) are specifically related. The propylene homopolymer or the propylene copolymer of the present invention has physical properties equivalent to or not lower than those of conventional propylene polymers, and it can be controlled in a melt tension and is suited to foaming molding, sheet molding and blow molding. Further, it is excellent in melt-processing characteristics, molding stability and a recycling property and can be applied to molding methods which are restricted in use in conventional propylene polymers, for example, large size blow molding and extrusion foaming molding.
